How to Clean an Oil-Fired Furnace

Without regular cleaning, an oil-fired furnace gets clogged with dirt, dust and debris, making it less efficient. Proper furnace cleaning keeps your furnace working all winter long, keeping your home warm and your family happy. Semi-annual cleaning, once in the spring and once in the fall, will keep your furnace in working condition throughout the winter.
